WATER-CLOSET.

of clogging ofthe bowl; in which the venting of the bowl may be accomplished whether the vent fiue be at the right or left of the closet, without the necessity of special molding; which will give a quick and noiseless action and certain refill; and in which sanitary conditions will be preserved under almost any use.

That .mydnvention may be clear to those skilled in the art I have illustrated in the drawings herewith one embodiment thereof, and in said drawings: Figure 1 is a sectional view of a closet embodying my invention. Fig. 2 is a diagrammatic plan to show the lay out of the connections, vent, &c: Fig. 3 is a sectional view of a slightly modified form. Fig. 4.- is a diagrammatm plan of the closet in Fig. 3 to give the lay out of the connections. Fig. 5 is a detail view of a.

slight variation in structure from that shown in the otherviews.

Referring to the drawings by numerals,

like numbers indicating like parts in the several views, and havin reference to Figs. 1 and 2 particularly, 2 esignates the bowl of the closet which 1s of the ordinary siphon type, generally speaking, having the usual trap or hopper, .siphon passa e, and soilpipe connection, to ether wit a flushing rim to which the ushing discharge flows through suitable perforations. The said bowl- 2 is connected with a tank 3, which in the present instance is shown as of the lowdown type supported on a raised tank-seat 4 projecting upwardly from rear of the bowl 2, by means of'a. suitable valve-controlled passage 5 (see dotted lines Fig. 1) which leads to the bottom of the siphon leg, where it terminates in a jet orifice 6 to induce siphoning.

on either side of the trap and communi-,

bowl and refill chamber shall be upward and trapping of air and annoying hissing is eliminated.

It will be obvious that after flushing, the surplus water in the refill chamber 8 will flow through orifice 9, by conduit 5, through jet opening 6, into the bowl to give the refill; and in drainingclosets in empty houses the arrangement oi these orifices and chambers is such that all of the water will drain ,to tllie lowest point without trapping in the The closet 2 has at its back an inclined apron or wall 10, which at its forward end forms practically a section of the elliptical seat opening, the seat proper 11, being of a U-shape with the-limbs oi the U extending toward the rear of the bowl, where they are trunnioned in suitable bearings 12? formed in the pottery or in any suitable manner. The saidwall 10 slopes upwardly to the top of the tank seat 4 and together with the top of the refill chamber forms a A vent passage 12, which, as shown in Fig. 1, extends upwardly and rearwardly and then downwardly and rearwardly, terminating in an outlet to the wall where it enters a vent flue (not shown).

It will be observed that while the relation of the vent terminal at the rear of the bowl is not altered perceptibly, being arranged substantially below the bowl top and out of the way of the low-down tank support, yet the bottom of the vent 12 is extended above the top of the owl 2, formin a dam intermediate the bowl and vent w ich is above the level of both, so that b no chance can the contents of a clogge bowl pass to the vent, but will overflow from the bowl itself, something much to be desired for obvious reasons; for a vent flue might be in bad sanitary condition without its being romptly discovered, and, furthermore, a ouled vent flue is difiicult to clean without tearing out the wall structure.

By reference to Fig. 2 it will be seen that while the seat 11 is discontinuous, the wall 10 practically completes the elliptical outpassage line of the seat, and being inclined upwardly forms an abutment which effectually prevents the occupant sitting too far back on the seat so that soilingof any of the seat parts is prevented.

Referring to Figs. 3 and 4 it will be seen that instead of leading the vent passage back beneath the tank to the vent flue, it is led directly to the tank, an independent connection 13 being provided towhich the vent passage 14; leads. The said connection 13 has a stand-pipe 15 rising therefrom which projects above the normal water level in the tank and serves two important purposes. First, it vents the closet bowl directly into the tank; and, second, it serves as an overflow in event of derangement of I the inlet and flooding of the tank. By providing this separate vent and overflo'w pipe, I am able to dispense with the usual overflow I =pipe leading beneath the valve, so. that the valve (which may be of any suitable type) will not be filled with air with the resultant blowing andhissing when the'air is expelled by inrush of water when the. valve is pulled but the valve and supply passages willcarry a'suspended column of water which will noiselessly flush when the closet is used.

The tank shown in Fig. 3 is put in communication with the vent flue through an '-opening.16 which may be cut in the rear attaching wall of the tank at any desired point dependent upon the line of'the vent flue, and since in my vconstruction the range of venting is limited only by the length of the tank, 1t will be seen that the closet bowl may all be made of one pattern and variatlons in position to accommodate vent flues be taken care of by cutting the tank open-v ing 16 to meet the position of the flue.

v This arrangement of venting the bowl through the tank has the further advantage of securing a proper ventilation of the tank itself, for by providing the opening 16 between the tank and flue all danger of improper circulation of air and consequent sweating and warping of the tank is eliminated.

In Fig. 5 I have shown a form in which the ventllatin feature is omitted, this form exhibiting" o y the refill feature and the inclined wall 17 in rear of the seat to complete the contourof the same, this particular form showingthe refill chamber 18 placed in the'upper part of the raised tank seat in rear of the bowl to the structural details disclosed, except in so far asI am limited by the art to which the invention belongs.

Having fully disclosed my-invention, I claim: 7 a

1. v A water closethaving a siphon passa e, -a supply' passage, and a vent; and a re 1 chamber the top of which extends upwardly into the vent passage above the top of the bowl and the vent outlet to form a dam between the bowl and vent.

- 2..A water closet having siphon passage, a supply passage having a jet opening to 'said siphon passage, a vent, a refill chamber having a jet connection with said supply passage and a top wall which projects upwardly into the vent passage above the top of the bowl to form a dam between the bowl and vent.

3. A water closet bowl having a substantially U-shaped seat opening rearwardly, a raised tank seat at the rear of the bowl and .an integral bowl projection sloping up- .wardly from the bowl rim to the tank seat so as to span the U-shaped seat and forming an abutment.

4. A closetbowl having an upward projection at its rear and provided with siphon and supply passages, and a separate refill chamber havingrbowl flushing openings in its front wall and located in said bowl projcction above. the normal water level of the bowl, the said siphon passage and refill chamber having jet connections with said supply passage, the said refill chamber .connection delivering at the bottom of the refill chamber.

5, A closet of the character described for use with low-down tanks having a bowl and a ventilating passage leading from the bowl in a straight line through the ware, the point of discharge of said passage being at the back of the ware, the lower wall of the ventilating passage near its forward end being nesses- JOSEPH w.
